We present a new track fitting algorithm for high energy physics experiments dedicated for handling the non-Gaussian detector effects. It uses a comprehensive propagation model to predict the particle trajectory, as well as flexible and parameterized models (FPM method) to describe the contributions from multiple scattering, to estimate of the positions of hits, and to calculate the energy losses. The track fitting algorithm with the FPM method then minimizes a global non-linear chi-square function to obtain the full information of a track.

一种新的轨道拟合算法，专用于使用灵活的参数化模型处理非高斯检测器效应

我们针对高能物理实验提出了一种新的轨道拟合算法，专门用于处理非高斯探测器效应。它使用一个综合的传播模型来预测粒子的轨迹，并使用灵活的参数化模型（FPM方法）来描述多重散射的影响，估计命中位置并计算能量损失。然后，使用FPM方法的轨道拟合算法将全局非线性卡方函数最小化，以获得轨道的完整信息。
